Can you open a .pst file out side of outlook

I have a .PST file that is no longer has permissions to be opened on my system.
There is no chance of getting the permissions changed.
So is there any other program besides outlook that can open this file?

The permissions to use personal folders and been removed from our network.
Unfortunatly not everyone transfered their personal folders before this change happened.
So i need to find a way to open the .pst file without using outlook.
